Mono(tm) Binary Kernel Support for Linux
  -----------------------------------------

  
  To configure Linux to automatically execute Mono-based .NET binaries
  (in the form of .exe files) without the need to use the mono CLR
  wrapper, you can use the BINFMT_MISC kernel support.
  
  This will allow you to execute Mono-based .NET binaries just like any
  other program after you have done the following:
  
  1) You MUST FIRST install the Mono CLR support, either by downloading

     a binary package, a source tarball or by installing from Git. Binary

     packages for several distributions can be found at:

  	https://www.mono-project.com/download/

  
     Instructions for compiling Mono can be found at:

  	https://www.mono-project.com/docs/compiling-mono/linux/

  
     Once the Mono CLR support has been installed, just check that

     ``/usr/bin/mono`` (which could be located elsewhere, for example
     ``/usr/local/bin/mono``) is working.

  
  2) You have to compile BINFMT_MISC either as a module or into

     the kernel (``CONFIG_BINFMT_MISC``) and set it up properly.

     If you choose to compile it as a module, you will have
     to insert it manually with modprobe/insmod, as kmod

     cannot be easily supported with binfmt_misc.
     Read the file ``binfmt_misc.txt`` in this directory to know

     more about the configuration process.

  3) Add the following entries to ``/etc/rc.local`` or similar script

     to be run at system startup:
  
     .. code-block:: sh

      # Insert BINFMT_MISC module into the kernel
      if [ ! -e /proc/sys/fs/binfmt_misc/register ]; then

          /sbin/modprobe binfmt_misc
  	# Some distributions, like Fedora Core, perform
  	# the following command automatically when the

  	# binfmt_misc module is loaded into the kernel
  	# or during normal boot up (systemd-based systems).

  	# Thus, it is possible that the following line

  	# is not needed at all.
  	mount -t binfmt_misc none /proc/sys/fs/binfmt_misc

      fi

      # Register support for .NET CLR binaries
      if [ -e /proc/sys/fs/binfmt_misc/register ]; then

  	# Replace /usr/bin/mono with the correct pathname to
  	# the Mono CLR runtime (usually /usr/local/bin/mono
  	# when compiling from sources or CVS).
          echo ':CLR:M::MZ::/usr/bin/mono:' > /proc/sys/fs/binfmt_misc/register

      else

          echo "No binfmt_misc support"
          exit 1

      fi

  4) Check that ``.exe`` binaries can be ran without the need of a
     wrapper script, simply by launching the ``.exe`` file directly
     from a command prompt, for example::

  
  	/usr/bin/xsd.exe

     .. note::
  
        If this fails with a permission denied error, check
        that the ``.exe`` file has execute permissions.
